A baghouse is typically composed of which components?

The correct choice highlights the essential components that make up a baghouse, specifically emphasizing its design and functionality in dust collection systems. A baghouse is primarily structured around its housing, which contains various filtration elements, and the hoppers designed to collect the dust that has been filtered out.

The tubesheet serves as a crucial part where the filter bags are mounted and provides support while allowing the filtered air to pass through. The plenum is vital for directing the airflow either into or out of the system, ensuring efficient operation. These components work together to create a system that captures particulate matter while allowing clean air to be released, which is the primary purpose of a baghouse.

While the other answer choices include components that may be found in industrial settings or dust collection systems, they do not specifically represent the typical and core structures that define a baghouse's operational design. Understanding the role of each component helps in better recognizing how a baghouse functions to maintain air quality and filter efficiency.
